Introduction

The ZP-SCB25A SPD surge backup protector (SCB for short) is an external disconnect device for the surge protector of the low-voltage power supply system, and can break the power frequency overcurrent caused by the failure of the surge protector. Both the circuit breaker function and the power frequency freewheeling protection function are integrated. SCB is used in series with SPD, suitable for power distribution and control systems with AC 50/60 Hz and rated working voltage 230/400V. It can effectively distinguish lightning current and power-frequency leakage current, and will not trip under the impact of large lightning current, and trip in time when power-frequency low current is applied, which can effectively prevent the SPD from catching fire when the power-frequency low current fails. And the greater the power frequency leakage current, the faster the tripping speed. The internal remote signal terminal can be integrated to feedback the status of the protector in real time.

Zhongpeng surge backup protector• Auto reclosing function 



For very important electrical equipment, once the SPD backup protector trips, the equipment will lose lightning protection.

SCB with auto-reclosing device is suitable for unattended important power distribution room,if SPD backup protector is intendedoutsidetrip,

Auto-reclosing can be reclosed immediately to ensure the continuous and effective lightning protection of the equipment!

Zhongpeng surge backup protector• SCB dedicated remote signaling contact 



SCB dedicated remote signaling contact accessory (1 normally open NO+1 normally closed NC) SCB can be installed on the side of the remote signaling accessory RS- 3.

When any extreme When the SCB is tripped, the closing switch drives the remote signal switch to actuate the remote signal switch.

installed on the side of the SCB, when any one-level SCB trips, it will send out a remote signal.
